Optica focuses on the rapid dissemination of high-impact results in all areas of optics and photonics. Optica is a dedicated venue for authors to publish high-profile research in both theoretical and applied optics and photonics.
To process information, photons must interact. However, these tiny packets of light want nothing to do with each other, each passing by without altering the other. Now, researchers at Stevens Institute of Technology have ...
